.the separate parts of my improvement are the end of said attachingv plate is prefer- 90 designated by suitable reference characters ably split -as shown at 24. in each of the views, and in which- Mounted upon' the outer face ofthe brake Fig. 1 is a plan view of a brake` band band lining strip 1G is a. thin inetal'strip 40 showing my improved lining mounted in 25 which is of considerable less transverse connection therewith; dimensions than the strip 16 and is ses 95 Fig. 2 a side view of the construction cured to the lining strip 16 by prongs or shown in Fig. 1; the like 26 stamped from the material of Fig. 3 a'longitudinal section through one the strip 25, as clearly shown in Figs. 3 end portion of the brake band with my imand 5 of the drawing. At predetermined proved lining mounted in connection there* points along the opposite side edgesof the with; lining strip 16 are secured pairs of guide Fig. t a detail view looking in the direcclips 27, which are secured to the strip 16 tion of the arrows 4 4 of Fig. v2; by prongs passed therethrough and com- 50 Fig. 5 a plany viewof the brake band pressed thereinto as shown a-t28 in Fig. 6

lining strip detached withparts of the conof the drawing, and said clips are provided struction broken away; and, with outwardly directed portions 29 which Fig. 6 a partial section on the line (3%6 are adapted to engage the side edges of the of Fig. 2 on an enlarged scale. brake band 10, as clearly shown in Figs.

2 and 6 of the drawing to hold the lining strip 16 against lateral displacement on said band 10. Y

The lining strip 16 is attached or mounted in connection with the brake band l() by passing the attaching plate 21, which is normally in an extended position between the bracket 13 and the usual drum 3() indicated in dotted lines in Fig. 2 of the drawing and moving the same around said drum until the attaching plate 17 is in proper position, in which operation the clips 27 will guide the lining strip 16, and when in proper position the free end o1" the attachingplate 2l is bent upwardly around the bracketv 12 as clearly shown in Fig. 2 ot the drawing, and the lining is now in position for use, and in the event of the wearing out or breaking of a portion of the lining strip 16, the metal strip 25 will serve to hold the same in position.

The distinctive features of the present invention is to provide a simple method of reinforcing the lining strip 16 by securing thereto a strip of thin metal 25 which vis of considerable less transverse dimensions than the strip 16 to produce a lexible lining strip, or a strip of this class which is capable of inserting or mounting upon brake bands regardless of their construction, and by providing theiseparate clips 27 which are independent of the strips 25 the entire lining strip is rendered flexible, and while I have shown specific forms of attaching plates on the ends of the lining strip 16, it will bey understood that I am not necessarily limited thereto, and other changes in and modifications of the construction herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacriiicing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is z- 1. A lining strip for brake bands provided on its outer face with a plurality or guide clips and with a narrow metal strip extending longitudinally of said lining strip, an attaching plate at one end of said lining strip, and .means for securing` said attaching plate in connection with the brake band.

A lining strip tor brake bands provided on its outer face with a plurality of guide clips and with a narrow metal strip extending longitudinally of said lining strip, an attaching plate at one end of said lining strip, means for securing said attaching plate in connection with the brake band, and another attaching plate on the other end of said lining strip and adapted to be securedto the other end portion of said brake band. l

3. The combination with a brake band provided at its free end with brackets, of

a lining strip for said band, said lining strip being provided at predetermined points with guide clips adapted to engage the side edges of said brake band for holding said lining strip against lateral movement thereon, an attaching plate at one end of said lining strip, said attaching plate being adapted to be secured to one of said brackets, and a narrow reinforcing strip mounted upon and secured to the outer face of said lining strip and extending longitudinally thereof.

4. The combination with a brake band provided at its free end with brackets, of a lining strip for said band, saidl lining strip being provided at predetermined points with guide clips adapted to engage the side edges of said brake band for holding said lining strip against lateral movement thereon, an attaching plate at one end of said lining strip, said attaching plate being adapted to be secured to one of. said brackets, and a reinforcing strip mounted upon and secured to the outer tace of said lining strip and extending longitudinally thereof, said strip being independent of said clips and being of considerably less transverse dimensions than said lining strip.

5. The combination with a brake band provided at its free end with brackets, ot a lining strip for said band, said lining strip being provided at predetermined points with guide clips adapted to engage the side edges of said brake band for holding said lining strip against lateral movement thereon, an attaching plate at one end of said lining strip, said attaching plate being adapted to be secured to one of said brackets, a reinforcing strip mounted upon and secured to the outer face of said lining strip and extending longitudinally thereof, said strip being independent of said clips and being of considerably less transverse dimensions than said lining strip, and an attaching plate on the other end of said lining strip and adapted to engage the other of said brackets for securely holding said lining strip in position. i

6. The combination with a brake band provided at its free end with brackets, ot' a lining strip for said band, said lining strip being provided at predetermined points with guide clips adapted to engage the side edges of said brake band for holding said lining strip against lateral movement thereon, an attaching plate at one end of said lining strip, said attaching plate being adapted to be secured to one of said brackets, a reinforcing strip mounted upon and secured to thev outer face of said lining` strip and extending longitudinally thereof, said strip being independent of said clips and being of considerably less transverse dimensions than said lining strip, and an attaching plate on the other end of said linstrip for holding said lining strip in prede-l termined position on ay brake band.

8. A brake band lining of the class described provided at one end with an attaching plate, means for securing said plate in connection with a suitable support, a reinforcing strip mounted upon and secured to the outer face of said lining strip, means independent of said last named strip and mounted in connection with said lining strip for holding said lining strip in predetermined position on a brake hand, and another attaching plate mounted in connection With the other end portion of said strip.

In testimony that I claim the foregoing as my invention I have signed my name this 2nd day of March, 1922.
